WITNESSES: 'fr A INVENTOR QMTRNEYS UNITED sTATEs PATENT oEEIoE.

HARRY M. HERR, OF LAMPETER, PENNSYLVANIA.

HINGE To all whom it may concern.'

Be it known that I, HARRY M. HERR, a citizen of the United States,residing at Lampeter, in the county of Lancaster and State ofPennsylvania, have invented certain new and useful Improvements inHinges, of which the following is a specification, reference being hadtherein to the accompanying drawing.

My invention relates to that class of hinges which comprise two leaves,pivoted together in a detachable manner, and has for its object toproduce a hinge that may be used as the top hinge of apair of hangingshutters,

doors, gates, etc., and provides a novel,.

cheap, durable and effective means for guiding and retaining the topleaf of the pair in position while the lower hinge or hinges are beingcentered, when by a slight motion to bring the leaves of the top hingeto a perpendicular position the upper hinge leaves will drop into place,thus doing away with the laborious and uncertain method of getting bothhinges in alinement together for hanging which is extremely hard to dowith a heavy shutter or gate.

While I have illustrated my invention as applied to a simple form ofdetachable hinge I do not confine myself to the exact form here shown,as a slight change may be made in the construction without departingfrom the spirit of the invention.

In the drawings like figures indicate corresponding parts in all figuresof the drawings.

Figure 1, shows the hinge as applied to the top pair on a shutter, inthe act of being hung. Fig. L., illustrates an elevation of the twohinge leaves in a detached position. Fig. 3, shows a plan top view ofthe same. Fig. 4, shows the device as applied to a gate.

1, indicates the lower leaf of a detachable hinge secured to a windowcasing, and provided at its lower half with the cylindrical enlargement2, from which extends upward the pintle 3, of smaller diameter than theenlargement 2, but concentric with it, thus providing a shoulder 4, uponwhich the upper member rests and turns.

Specification of Letters Patent.

Application filed November 22, 1907.

Patented Sept. 15, 1908.

Serial No. 403,345.

The upper leaf 5, is secured to the shutter in the usual way, and isprovided with the cylindrical socket 6, extending from its upper halfand adapted to slip over and embrace the pintle 3, of the lower leaf,thus completing the hinge. Upon the top of the pintle 3, on the rearside thereof, is provided the ledge or shoulder 7, formed by slightlyrounding or raising the end of said pintle 3, by an elliptical extension8, upon which the upper hinge leaf may rest,

The mode of operation of my device is as follows: Supposing the leaf l,of the hinge to be secured to the window casing and the leaf 5, to theshutter near its upper end, and a plain pair of hinge leaves secured tothe window casing and shutter near their lower ends. The shutter israised by the hands of the operator and the lower back edge of thesocket 6, of the leaf 5, rested upon the shoulder 7, of the lower leafwhich will support the weight of the shutter and allow the upper leaf ofthe lower' hinge to pass freely over the pintle of the other Ieaf of thelower hinge until the operator gets them in alinement, when by a slightpush of the upper part of the shutter backwards the edge of the socket6, is pushed off of the shoulder 7, allowing the shutter carrying theupper leaf of the hinge to drop into engagement with the lower leaf, andthe shutter then hung in place.

I/Vhat I claim as new and desire to secure by Letters Patent is z- In adetachable hinge of the vclass described, having the lower leaf providedwith a pintle extending beyond the socket of the upper leaf, a shoulderformed upon the top of said pintle at the rear side thereof, for thepurpose set forth.

In testimony whereof I afl-lx my signature in presence of two witnesses.
